I always like to start early with the habits that I want students to retain, and one of them is: Don't do anything else in a turn if you can avoid it.
It isn't a question of what the aircraft will stand, but a lot of my students go on to Instrument Ratings, and the pressure in imc can be substantial especially when handflying on single-pilot ops, so in a turn you just turn, that's all. Most aeroplanes are unstable in roll beyond about 5 degrees, so once you're past that, as in a normal turn, it's time to focus on the main game. If it happens to be a climbing or descending turn, then it's even more important to just do the basics first, and then deal with flaps/radio/gear/etc once the turning part is completed.
Of course, we're on opposite sides of the world, and I'm betting it's a very different training environment so your mileage may vary, but that's why I teach it here.
